The blue is a french blue with gray undertones and is upholstered in a nice soft microfiber. This chair adds a nice touch of color to my office without being too bold. It was pretty easy to assemble without instructions. The back and seat are contoured, and at my height of 5'6", the back support, though not adjustable, fits right in the small of my back. The neumatic lift works great for getting that just right height and the casters roll smoothly.
I have been shopping for an office chair for quite awhile and this one is perfect for a couple hours of computer use. This chair would get 5 stars for price, quality and comfort, but I haven't had it long enough to know how well it will hold up; although, it appears to be quite sturdy.
I shop at Overstock quite often and am very pleased with overall product quality, price and customer service. My advice for Overstock shopping success is to read reviews, pay attention to measurements, compare prices and use the Chat service if you have questions.
